Judging from the effect of paying attention to physical and mental integration in sports, spinning needs to mobilize more body muscles. So both are aimed at losing weight: obviously spinning is better than running.

Bikes are better! But all sports need persistence to achieve results.

Many sports don't exercise for a few days, which is easy to rebound!

It depends. The metabolic equivalent of running and cycling is different under different conditions. For example, when running, the faster the speed, the greater the metabolic equivalent (MET). When the speed is constant, the greater the slope, the greater the MET. Similarly, the relationship between bicycle weight and power is the same as above, and power must be the greater the weight, the greater the MET, and vice versa. It depends on your personal situation, which way you like, which way you are more suitable for, or the energy you need to consume at the same time.

Met (metal equivalent energy), transliterated as Met, is defined as engaging in activities for one minute per kilogram of body weight, consuming 3.5ml of oxygen, and its activity intensity is called 1MET. That is, 1MET=3.5mlO2/kg? Points. The greater the MET value, the greater the exercise intensity of the event, and the activity intensity of 1MET is approximately equivalent to the basic metabolic level of adults.
